## 8 How to fool it

Actually, the MQI subroutine cannot be fooled. In the worst
case, it gets exactly the right answer.

However, the overall heuristic method of (bisection proposer)+MQI
can be fooled. Just build the cartesion product of a graph with
a good bisection and a graph with a better 1/3-balance quotient cut.
One can arrange for the result to be any factor worse than the optimum.
